Changing Backgrounds and Wallpapers in KDE Plasma

Turns out there are a few places to change desktop backgrounds in KDE Plasma.

There is of course the standard desktop for logged in users. Each monitor has its own wallpaper settings so you need to individually right click each desktop and select Desktop and Wallpaper to choose the background.

But then there are two places to change the background for wha we old Windows users would think of as the “lock screen”.

The first is displayed when there is no user logged in at all … so when the system first boots up. This one is configured through System Settings > Appearance & Style > Colors & Themes > Login Screen (SDDM) … then click the picture icon which is sitting on the selection of theme you have in use.

The other is the actual lock screen. This is for when the user has locked the screen on purpose or through timeout. This one is controlled at System Settings > Security & Privacy > Screen Locking … and then click the Configure Appearance button in the top right of that window.

Who knew, eh? Oh .. Duha knew and wrote it all down for me. Thanks!
